Abstract

Various examples and schemes pertaining to channel access priority class (CAPC) for uplink (UL) transmissions in New Radio (NR) unlicensed spectrum (NR-U) are described. An apparatus implemented in a user equipment (UE) receives, from a network node of a wireless network, a radio resource control (RRC) configuration indicating a first channel access priority class (CAPC) for one or more logical channels. The apparatus determines a second CAPC to be used for a listen-before-talk (LBT) procedure. The apparatus then performs the LBT procedure using the second CAPC to detect whether a channel is clear for transmission.
